The present invention relates to a glass-ceramic article comprising at least one substrate, such as a plate, made of glass-ceramic, said substrate being coated in at least one area with at least one enamel coating such that:

Glass-ceramic article

The present invention relates to a glass-ceramic article at least partly coated with at least one layer of an enamel formed from a glass frit having the following composition, the proportions being expressed as weight percentages: 

Glass-ceramic article and enamel suitable for the coating thereof

Enamel composition, in particular intended for covering a glass pane of a fireplace insert, comprising at least one glass frit, at least one pigment in a content varying from 40 to 65% of the total weight of the enamel, preferably from 45 to 60%, and optionally at least one vehicle or medium, characterized in that the glass frit comprises the following constituents, within the limits defined below, limits included, expressed as percentages by weight of the total weight of the frit: 

Enamel composition for glass-ceramic

A glass-ceramic plate for covering or accommodating at least one heating element, wherein the plate is at least partly coated with at least one nanoscale layer based on a metallic material having a refractive index greater than the refractive index of the glass-ceramic.

Glass-ceramic plate and its manufacturing process

A process for reinforcing a glass-ceramic article, into which a maximum tension is introduced beneath the surface of the glass-ceramic, advantageously in proximity to said surface. The invention also relates to an enamel that can be used for this reinforcement, this enamel being formed from a glass frit having the following composition, the proportions being expressed as weight percentages: the sum of the alkaline-earth metal oxides CaO+BaO moreover being between 8 and 15%, and the sum of the alkali metal oxides NaO+KO+LiO moreover being between 7 and 20%. The reinforced glass-ceramics obtained by the process.
